1. An apparatus comprising:

  • a user interface configured to generate an electrical signal to begin determination of an effective correction factor when prompted by a user, wherein the determination of the effective correction factor includes delivery of an initial correction bolus;

    an input configured to receive sampled blood glucose data of a patient that is obtained during a specified time duration, including a time duration after delivery of the initial insulin correction bolus; and

    a controller communicatively coupled to the input and the user interface, the controller including a correction factor module configured to;

    calculate an effective correction factor using an amount of insulin in the initial insulin correction bolus and a decrease in the blood glucose level determined by the controller using the sampled blood glucose data; and

    cancel the determination of the effective correction factor if a blood glucose level of the patient is outside of a specified range of blood glucose levels.
